Title: Phase compensation controlling system of return signal
Inventor: HAMADA SHIGERU
IPC: H04B17/00
Filed: 1981-09-16
Abstract: PURPOSE:To stabilize the compensation of phase for a mobile communication system, by discriminating the signal frequency for monitor of receiving talking circuit of a talking circuit before setting the talking circuit and setting previously the corresponding degree of phase compensation. CONSTITUTION:For a mobile communication system which monitors a talking circuit and measures the distance between two stations, the SAT signal frequency discrimination code for monitor of talking circuit which is transmitted previously is reproduced at a data receiving part 26 through a control circuit and before the talking circuit is set. The discrimination code is then transferred to a central processing part 27 to be used for necessary processes and for control of the terminal device. The degree of phase compensation corresponding to the SAT frequency which is designated by the SAT frequency discrimination code is read out of a storage part 28 among the discrimination codes at the part 27. Based on this data of the part 28, the degree of phase shift is set for a variable phase shifter 24. In such a way, the accurate compensation of phase is made possible to the designated SAT frequency.

Abstract: PURPOSE:To prevent adsorption power from getting deteriorated by carrying out one by one in turn the processes of adsorbing with a first column and a second column connected in-line, cleaning the first column with the pressure reduced gas of a third column, pressure reducing and evacuating the first column and equalizing the pressure of the second column with that of the third column. CONSTITUTION:A first column and a second column packed with zolite group are connected with in-line in a line 5, raw material gas containing N2, CO2 and moisture being introduced into the first column to adsorb CO2 and moisture, while discharging non-adsorbing gas out of the second column. A third column is vacuum extracted, and CO2 and moisture are recovered as product gas. Next, part of desorbed gas from the third column is introduced into the first column for cleaning. Further, the first column is vacuum extracted and the second and third columns are connected in a line 6 for carrying out the pressure equalization process. After that, the connected second and third columns go into the adsorbing process. The cycles of processes similar to the above repeatedly carried out, but the columns are shifted to the following ones in such as manner as to shift the first column to the second, the second to the third, and the third to the first. CO2 and moisture are thus separated and recovered.

Title: Method and device for measuring turbidity of liquid
Inventor: NAKAMURA HISASHI
IPC: G01N21/15
Filed: 1984-07-12
Abstract: PURPOSE:To obtain an accurate measured value which is not affected by bubbles by jetting air to a photodetection surface intermittently and cleaning the photodetection surface, and then floating and separating air bubbles in a measurement cell and measuring the scattered light of liht with which liquid to be measured is irradiated through a sensor. CONSTITUTION:The device is dipped in the liquid to be measured in an on-line state and set so that the photodetection surface 5 faces above the horizontal. Namely, when the liquid to be measured is liquid flowing in a pipe, the device is fixed where the opening 6 of the measurement cell 2 faces above the horizontal. Then, an electromagnetic valve 8 is turned on at constant intervals of time to blow air from an air nozzle 7 to the photodetection surface 5 intermittently. Consequently, dust sticking on the surface of the photodetection surface 5 is cleaned away together with the liquid to keep the surface invariable clean and prevent liquid from staying in the measurement cell 2, which is then filled with invariably fresh liquid. When the blowing of the air is stopped, air bubbles in the measurement cell 2 are separated by floating upward, and the turbidity is measured after air bubbles separate from the liquid completely.
